nitrate of soda and a small amount by bone tankage. It i'fe tme 

 that only small amounts of water insoluble nitrogen were found 

 present in the two brands, most of the nitrogen being in the form 

 of ammoniatcs and nitrates; yet the low activity shown on the 

 water insoluble portion indicates that its source was other than 

 bone tankage. ; 



The Berkshire Fertilizer Company claim that in case of their 

 Complete Fertilizer sufficient animal tankage, nitrate of soda and 

 sulfate of ammonia were used to meet the minimum guarantee 

 (2.5%). They state that 100 pounds of beet root manure and a 

 little over 100 pounds of grape pomace were added as a filler which 

 was not counted in the guarantee. In case of the Ammoniated 

 Bone Phosphate, the claim is made that sufficient high grade tank- 

 age was used to furnish the nitrogen up to the guarantee. Ground 

 grape pomace and garbage tankage were used in place of filler con- 

 taining no fertilizing value. This explanation is reasonable as in 

 both cases the fertilizers showed an overrun of nitrogen, the com- 

 plete fertilizer .2% and the ammoniated bone phosphate .64%. 



The Buffalo Fertilizer Company state that some garbage tank- 

 age was used in the low grade brands, but more as a filler and to put 

 the goods in perfect mechanical condition than as a source of am- 

 monia. They depended upon this source for the excess over the 

 minimum guarantee. They state further that another spring.no 

 garbage tankage at all will be used except as a filler or drier. It 

 might be added in this connection that the brands in question ran 

 only from .1 to .2% over the lower guarantee. 



The E. D. Chittenden Company state that the base mixture 

 from which their goods were made tested 84% availability prior to 

 the manufacturing of the goods. They also state that a further in- 

 vestigation will be made and a later report furnished, but no fur- 

 ther explanation has come to hand. 



The Coe-Mortimer Company claim that early in the season 

 they used considerable low grade calciimi cyanamid, which con- 

 tains quite a proportion of peat, added for the purpose of allaying 

 dust and producing a good mechanical condition. The claim made 

 by the producers of the cyanamid product was that the nitrogen 

 in the peat was rendered available during the process of manufac- 

 ture. As soon as it was discovered that the nitrogen in the peat 

 was not available, the use of the cyanamid product was discon- 

 tinued. It is their belief that the goods taken by our inspectors 

 were from shipments where this cyanamid product had been used. 



Mapes^ Formula and Peruvian Guano Company have the fol- 

 lowing to say : "We furnish almost all of the nitrogen in the form of 

 soluble nitrate and ammonia salts. The organic nitrogen is very 

 low, coming from the special grades of degelatinized bone meal and
